The documentation for HMC Version 7 says that the web browsers supported are Microsoft Internet Explorer 6.0 and later, as well as Firefox 1.5.0.6 and later. While many users have no trouble with Internet Explorer 7.0, others have reported problems. What makes the difference? Sometimes its Java code, and sometimes its the browser settings. For example, a customer recently reported trouble with IE 7 after he updated Java to jre 1.6.0_05 from jre 1.6.0_03. Previously, IE 7 had worked fine. IBM support usually will make a best-effort attempt... [More]

Be sure you order the correct Hardware Management Console to match the code you plan to run. The 7042 machine type is for HMCs running Version 7. This Licensed Internal Code is a requirement for managing POWER6 servers, such as the 9117-MMA. However, it will also support POWER5 and POWER5+ managed servers. The 7310 machine type is for HMCs running Version 6. You cannot manage a POWER6 server using this HMC code. It is for POWER5 and POWER5+ managed servers only. Many 7310 HMCs can be upgraded in the field to support HMC V7 Release 3 code. ... [More]

Configuring MPIO for the Virtual Client , describes how to set up Multi-Path I/O boot disks for AIX clients of the virtual I/O server. There some considerations for booting off the SAN. The "pro's" include: IBM supported configuration Flexibility The "con's" include: If the SAN fails Can not capture an AIX dump file (Consider putting dump space on an internal disk) Lose the ability to diagnose the failure from the server side. Updating MPIO on the AIX client may be disruptive (depends on MPIO vendor/version) "Momentary SAN stalls" can cause... [More]

I use the following formula to size the minimum number of cores on replacement servers. The formula is based on "used" performance on the installed servers matching "used" performance on the replacement server. c2 = (u1)(c1)(p1) / (u2)(p2) Where c1 = # cores on the installed server p1 = "performance per core" of the installed server u1 = % utilization of the installed server c2 = # cores on the replacement server p2 = "performance per core" of the replacement server u2 = % utilization of the replacement server If consolidating multiple...
